Abstract
Objective. To establish the ability of lower crustaceans Daphnia magna to maintain the existence in the aquatic environment of pathogenic bacteria Erysipelothrix rhusiopathiae - causative agents. Methods. Daphnia was infected by bacteria E. rhusiopathiae through water. During the experiment, the bacteria content in the crustacean and water organism was determined. Results In the experiment, planktonic crustaceans D. magna were infected with E. rhusiopathiae bacteria through water. Pathogenic bacteria isolated from the body of Daphnia for 20 days, and from control samples - 6 days. Conclusions Lower crustaceans D. magna are capable of sustained time - 20 days (observation time) to maintain the presence of pathogenic E. rhusiopathiae bacteria.

Key words: Erysipelothrix rhusiopathiae, Daphnia magna, duration of existence.
